Ok, unlike Chief my motor is a 40hp. It ran fine a couple of wks ago,started 1st everytime and all. Took it to the river sun. and it wouldn't start for anything. I checked /charged the battery but didn't think that was the problem anyway. The starter sounds strong and the problem is it won't turn over. I changed the sparkplugs and still the same thing, it's like it won't spark or it's not getting any fuel. I have no experiencew/ engines and the boat only has 47hrs on it. The owners manual isn't all that detailed either.
